Why does reading comprehension decrease when text is displayed using a font with highly variable character widths on a mobile device in direct sunlight?

💡 Explanation

Reading comprehension suffers because variable character widths, exacerbated by sunlight glare, disrupts the normal saccadic eye movement patterns during reading; this makes it harder to predict the next character, therefore cognitive load increases rather than being optimized by consistent spacing.
